Presidents' Day, also known as Washington's Birthday, is
a national holiday in the United States of America celebrated on the third
Monday of February. It is an amalgamation of two previous holidays, Lincoln's
Birthday (February 12) and Washington's Birthday (February 22).

In American elementary schools the days leading up to President's Day
are often used to educate students on the history of the Presidents of
the United States, especially former Presidents George Washington and
Abraham Lincoln.

In recent years President's Day has become well-known for being a day
in which many stores hold sales.

Observance on the third Monday of February dates to the Monday Holidays
Act of 1968, which became effective in 1971. A draft of that bill called
for a Presidents' Day to honor both Washington and Lincoln, but the final
version only moved Washington's Birthday from February 22 to the third
Monday without changing its name. In 1971, President Richard Nixon issued
a proclamation calling for a Presidents' Day on the third Monday to honor
all US presidents, but that did not have the force of law. As of 2003,
the federal government still refers to the holiday as Washington's Birthday,
while many state and local governments and private employers refer to
it as Presidents' Day.

Adding to the confusion is that George Washington's birthday was nominally
on February 11, but in the Julian calendar that predated England's calendar
reformation in September 1752. His birthday is equivalent to February
22 in the Gregorian calendar used today
